The 8" x 4" Wye Solvent Weld fitting is engineered to provide a smooth, low-turbulence branch connection in underground sewer and drainage systems. Designed with a 45° branch angle, this wye fitting allows for efficient gravity-fed flow from a 4" lateral pipe into an 8" mainline, minimizing clogging and hydraulic loss. Made from durable PVC with solvent weld socket ends, it meets ASTM standards for sewer applications and ensures a secure, leak-resistant installation.
